摘要：
A purification method for a biological fluid comprising at least a filtration step through a membrane obtained from a sulfone polymer (PSI) derived from bio-based feed-stocks. In particular the polymer (PSI) comprises more than 50% moles recurring units (RPSI) comprising sugar moieties selected from the group consisting of those of formulae (E′-I) to (E′-III):
A membrane free from pore-forming agents comprising at least one sulfone polymer (PSI) and a method for preparing such a membrane.
A membrane free from pore-forming agents comprising at least one sulfone polymer (PSI) and a method for preparing such a membrane.
